Voice biometrics, meaning speaker recognition, identification and verification technologies should never be confused with speech recognition technologies.
Speech recognition technologies have the ability to recognize what a person is saying but do not recognize who the person is. Applications of speech recognition for security purposes or secure transactions are therefore limited.
By contrast, speaker recognition, verification and identification technologies can be used to ascertain if the speaker is the person he or she claims to be.
According to leading voice–based biometrics analyst J. Markowitz, Consultants:
• Speaker identification is “the process of finding and attaching a speaker identity to the voice of an unknown speaker. Automated speaker identification does this by comparing the voice with stored samples in a database of voice models.”
• Speaker verification is “the process of determining whether a person is who she/he claims to be. It entails a one-to-one comparison between a newly input voiceprint (by the claimant) and the voiceprint for the claimed identity that is stored in the system.”
CellMax Systems is both a speaker identification and speaker verification technology.
